SkyGateway/SkyExtender Installation And Configuration C HAPTER 1 I NTRODUCTION A SkyPilot System is made up of the following components:

. This network element provides an interface between the SkyGateWay network and the Internet or WAN via a 10/100BASE-T connector. A minimum of one SkyGateway unit is required for a SkyPilot System;

additional units provide redundancy in case of a power failure or other problem at the main gateway. These nodes connect directly to a SkyGateway device, to SkyExtender other SkyExtender nodes, and to SkyConnector Indoor and SkyConnector Outdoor subscriber units. They provide the framework of the network. A SkyExtender is typically installed on a roof, tower, light or utility pole, or other fixed location. In a rooftop installation, a 10/100BASE-T Ethernet connection is available for subscriber usage. SkyConnector Indoor and SkyConnector Outdoor

. These units are installed in subscribers homes or offices. A SkyConnector provides an interface between the subscribers computer and the network. The interface between the SkyConnector and the network is via a wireless connection to a SkyExtender. The interface to the subscribers computer is via an Ethernet cable. The outdoor unit typically provides greater range than the indoor unit and is normally installed on an eave or roof. The indoor unit is installed on a windowsill or in a window frame by the subscriber without a truck roll and offers simple plug-and-play configuration. This manual provides instructions for installing and maintaining SkyGateWays and Sky Extenders. See the SkyConnector Outdoor Unit Installation Guides products. SkyConnector Indoor Unit and for information about those September 2004 1-1 SkyGateway/SkyExtender Installation And Configuration Guide System Overview SkyGateWay basestations and SkyExtender nodes form the backbone of a SkyPilot System. Both devices feature:

A compact, lightweight design that permits easy installation in a wide range of loca-

tions. High-power, 360 coverage. An efficient single connection for both power and data. SkyGateWay and SkyExtender units are virtually identical, differing only in their soft-

ware. SkyGateWay basestations use a superset of the SkyExtender software that includes the necessary programming to communicate with an external network. The SkyExtender is comprised of five separate modules: baseband motherboard, mPCI radio module, switchboard, and antenna array. Physical Specifications and Installation Each SkyGateWay or SkyExtender is only 18 inches high, 12 inches in diameter, and 14 pounds in weight. The compact size and light weight mean that these units can be installed on existing structures such as utility poles, commercial buildings, homes, billboards, and water towers. Each unit comes with a mounting bracket that fits over a standard 1.25-inch-diameter pole. Operating temperatures can range from -40C to 55C (-40F to 130F). Power Antennas Modules Because they use Power over Ethernet (PoE) and draw only about 10 watts, the only cabling these units require is CAT-5 Ethernet cable. There is no need to lease dedicated poles or run power cables, and no special tools are required for installation. The eight antennas in a basestation or node provide sectorized 360 coverage. Each antenna has a horizontal beamwidth of 45, a vertical beamwidth of 6.5, and a gain of 18 dBi. The motherboard has a PowerPC CPU, volatile and non-volatile memory, a DC power interface, and interfaces to other system components. An mPCI radio enables a SkyGateWay or SkyExtender to transmit and receive in the 5.8GHz band using modulation rates of 6 to 54Mbps, providing a peak EIRP of 44.5 dBm (28.2W). The radio currently supports a range of center frequencies from 5745MHz-5805MHz. Each channel is 20MHz wide and can configured on 5MHz frequency granuality. Up to 4 non-

1-2 September 2004 SkyGateway/SkyExtender Installation And Configuration overlapping channels can be supported. In an environment free from significant interference in the UNII band, as many as four SkyGateWay or SkyExtender units can be installed at a single location, each configured to use a different channel. The radio module also contains the wireless MAC and Physical Layer logic, implementing the 802.11a hardware specification via an Atheros chipset. The radio module connects to the motherboard for data and to the switchboard for RF. A switchboard provides the connection between the radio and the antenna array. It provides antenna selection and amplifies the radio signal. An integrated GPS receiver in both SkyGateWay and SkyExtender basestations is used by SkyControl software to synchronize transmissions within the network. It connects directly to the motherboard. The GPS antenna is positioned on top of the antenna array assembly inside the SkyGateWay enclosure. A RJ-45 jack enables a SkyGateWay to receive power and connect to an external network. The same jack on the SkyExtender is normally only used for power, but can also be used to connect directly to a subscribers network or computer. (Both units come with a Power over Ethernet injector module that combines incoming data and power onto one Ethernet jack that connects to the SkyGateWay or SkyExtender device.) An optional serial adapter (RJ-45 connector) permits local access to a command-line interface (CLI) to change the units settings. Connectors September 2004 1-3 SkyGateway/SkyExtender Installation And Configuration Guide Physical and Link Layers Routing Network Architecture The SkyPilot system software manages communications protocols at all levels, from RF to routing. It carefully manages SkyGateWay, SkyExtender, and subscriber nodes to create the best possible network performance. SkyProvision software is used to configure the system. The SkyPilot System operates as a Layer 2 network. All subscriber traffic goes to and from the network via an external switch or router attached to the Ethernet bridge in a SkyGateWay basestation. Peer-to-peer communication is not permitted within a SkyPilot System. Physical Layer

. At the RF layer, the components of a SkyPilot System use standard 802.11a modulation operating in the 5.8GHz range. The Physical Layer SkyPilot protocol conforms to the 802.11a specifications with the addition of a synchronous one-second frame. The timing of this frame is derived from a GPS receiver in each SkyGateWay and SkyExtender. The frames signal is used to control transmission and reception in the network, and also provides a reference for the hello message exchange (a beacon/

response sequence that allows nodes and gateways to establish connections). Data Link (MAC) Layer synchronization protocol that takes advantage of the one-second RF frame to establish links and exchange secure, rate-controlled data between devices. At the MAC layer, SkyPilot implements a Above the MAC layer, SkyControl brings into play a dynamic routing protocol that ensures the most efficient utilization of network resources and provides for rapid rerouting around link and device failures. SkyControl allows SkyExtender nodes and SkyConnector subscriber units to join the network automatically. When a SkyExtender node connects to the network, it selects an optimum route to a SkyGateWay. The route selection considers link capacity

(modulation rate), and the number of hops between the node and the gateway. Once a route is selected, all user traffic is forwarded via this path unless conditions change. Rerouting is necessary (and automatic) when a link or node is lost. The SkyPilot system also automatically reroutes traffic when it determines that a lower cost route is consistently available. (A connections cost is determined by the number of hops it requires and the modulation rates on each of the connections component links.) 1-4 September 2004 Scheduling and Bandwidth Management SkyGateway/SkyExtender Installation And Configuration As mentioned, the SkyPilot System supplements the 802.11 protocol with sophisticated synchronization. By transmitting over different antennas in different 100us mini-slots of the one-second synchronization frame, a SkyPilot basestation or node provides 360 coverage through multiple high-

power point-to-point connections. In addition, highly accurate traffic rate control and jitter control are enabled. Bandwidth management within a network presents a particular challenge due to the high number of interconnections, with each SkyExtender node typically communicating with a multitude of others. The SkyPilot system ensures that mini-slots are provided over each link, with the number of mini-

slots used by each pair of nodes varying as subscriber bandwidth demand changes. The SkyPilot system provides rate control for subscriber traffic both in the downstream (SkyGateWay to SkyConnector) and upstream (SkyConnector to SkyGateWay) directions. Maximum upstream and downstream rates can be specified for each subscriber. In conditions of oversubscription, when the overall bandwidth demand is higher than system capacity, the individual subscriber data rates will be reduced proportionately.

1. Plan The Installation 2. Unpack The Equipment 3. Mount The Unit 4. Install Cabling September 2004 2-1 SkyGateway/SkyExtender Installation And Configuration Guide Site Survey Plan The Installation In a typical wide-area wireless network utilizing SkyPilot units, the SkyGateWay is installed on the roof of a tall building or tower. The direct coverage area of the SkyGateWay is generally proportionate to the height of the installation. A SkyGateWay may also be used in smaller scale networks. Examples include high-

capacity business or academic campus interconnection, or a localized access network. In this case, the SkyGateWay could be installed on a local, medium height building or utility pole. The SkyExtender may be installed on home rooftops, tall buildings, or on light or utility poles. Refer to the Site Planning document for more information. Frequency SkyPilot recommends that an operator utilize a spectrum analyzer to scan the UNII spectrum prior to installing one or more SkyGateWays. This information will be SkyPilot Network necessary later when configuring the frequency. See the Management Guide

September 2004 3-1 SkyGateway/SkyExtender/Installation And Configuration Guide Connecting Via a Serial Link SkyGateway signals its presence through the use of a periodic beacon message transmitted on the configured frequency. When a SkyExtender or SkyConnector is installed, it listens for this network beacon message. When a beacon is received, the SkyGateway responds and attempts to establishment a link. In the event you need to troubleshoot the SkyGateway from the console, perform the following steps. 1. Connect a DB-9 cable to the Serial Port. 2. Connect to a laptop. 3. Set baud settings at 38,400 and N81and run the terminal emulation program. The unit will begin to search in a circular pattern for a nearby SkyExtender or SkyGateway. This can take up to two minutes.
